Potential intrinsic

The convolution analysis is based on the use of convolution data and further manipulation to obtain information on the ET mechanism, standard potentials, intrinsic barriers, and also to detect mechanism transitions. It is worth noting that the general outlines of the methodology were first introduced in the study of the kinetics of reduction of terf-nitrobutane in dipolar aprotic solvents, under conditions of chemical stability of the generated anion radical. For the study of concerted dissociative ET processes, linear scan voltammetry is the most useful electrochemical technique. [Pg.99]

Steps 3-5 are strictly chemical and consecutive to each other Hougen-Watson-Langmuir-Hinshelwood rate equations describing the rate of the purely chemical phenomenon consisting of steps 3-5 have been derived in Chapter 3 on the kinetics of catalysed reactions. In the transport-limited situation the supply of reactant and/or the removal of reaction product will not be sufficiently fast to keep pace with the potential intrinsic rate, and the concentrations of A and B inside the pores will be different from the corresponding concentrations in the bulk of the fluid phase. [Pg.397]

In configurations shown in Figures 6.13 and 6.14 the output voltages of the two DC/DC (or AC) converters (or inventors) must be set the same for evenly sharing the load. However, due to the potential intrinsic inaccuracy in the voltage set points of the two DC/DC (or AC) converters (or inventors) and the iR losses through the wire between the DC/DC (or AC) converters (or inventors) and the electric motor, the power sharing between the two DC/DC (or AC) converters (or inventors) may become tricky. [Pg.253]

The study of electroreduction of chromium trichloride in the NaCl-KCl melt conducted in [10] showed that the equilibrium potential of platinum in this melt overlaps partially the region of the recharge potentials intrinsic to Cr(IH) complexes. As a result, platinum can dissolve via the reaction... [Pg.255]

Peierls instability indicates why a half-filled energy band is split up, resulting in a completely filled valence band and an empty conduction band separated by a forbidden zone, the so-called bandgap. Understanding this mechanism is of fundamental importance because it allows insight into why potential intrinsic conductors appear to be intrinsically insulating in the undoped state. [Pg.34]

Unfortunately, the approach of determining empirical potentials from equilibrium data is intrinsically limited, even if we assume complete knowledge of all equilibrium geometries and their energies. It is obvious that statistical potentials cannot define an energy scale, since multiplication of a potential by a positive, constant factor does not alter its global minimizers. But for the purpose of tertiary structure prediction by global optimization, this does not not matter. [Pg.215]

Electrophoresis uses the force of an apphed electric field to move molecules or particles, often through a polymer matrix. The electric field acts on the intrinsic charge of a substance, and the force on each substance is proportional to the substance s charge or surface potential. The resulting force on the substance results in a distinct velocity for the substance that is proportional to the substance s surface potential. If two different substances have two different velocities, an electric field apphed for a fixed amount of time results in different locations on the matrix for these substances. [Pg.178]

Note that low carbon or stabilized grades of stainless steel do not possess intrinsically greater corrosion resistance than their unadjusted counterparts. Their sole value in typical cooling water systems results from their resistance to sensitization and potential weld decay that can result when the metals are welded. It is therefore not economically justifiable to specify low carbon or stabilized grades of stainless steel for typical cooling water system components that are not to be welded. [Pg.342]
